Summary
This review details normal orbital anatomy visualized using MRI and CT scans. It covers key structures like the bony orbit, optic nerve, muscles, and lacrimal system for diagnostic reference.
Area of Science:
- Ophthalmology
- Radiology
- Anatomy
Background:
- The orbit contains complex human anatomy, posing diagnostic challenges.
- Evaluating orbital structures requires advanced imaging techniques.
Purpose of the Study:
- To review and illustrate normal orbital anatomical structures.
- To aid in the diagnostic evaluation of orbital conditions.
Main Methods:
- Review of normal orbital anatomy.
- Illustration of structures identifiable on CT and MRI.
Main Results:
- Detailed identification of bony orbit, globe, optic nerve, extraocular muscles, lid retractors, fibrous framework, vasculature, nerves, and lacrimal system.
- Demonstration of anatomical relationships within the orbit.
Conclusions:
- CT and MRI are crucial for visualizing normal and abnormal orbital anatomy.
- Understanding normal orbital structures is essential for accurate diagnosis.
